Kentuckians on Medicaid now have the opportunity to change healthcare providers for the first time in months.Open enrollment for all of the state except Louisville started today. It's the first time since Medicaid was privatized that residents can choose a new private operator to handle their care.Kentucky has three statewide operators: CoventryCares, WellCare and Kentucky Spirit. Many doctors and hospitals have had problems with Coventry's reimbursement rates for procedures. And many Eastern Kentuckians have already announced plans to switch to another provider. But an exodus of patients to another provider could simply shift the problems, not solve them.Open enrollment ends on October 19. Any changes will become effective November 1.
